First three articles of antennae sparsely hirsute, the other with 

 the usual fine short hairs. 



Dental plates low, each convex. 



First dorsal plate with cervical sulcus free, strongly angled at 

 middle, the angle in a depression. Paired longitudinal sulci 

 furcate, their inner branches running as usual to the angle of the

 also bearing along mesal surface three spinules and along dorso- 

 mesal edge six; also a series of about six similar spinules along 

 ectal surface. Tibia in median ventral line with two spinules,
